2PCS TMC2208 V1.2 3D Printer Stepper Motor Driver, Upgrade TMC2208 Stepper Driver Module with Heat Sink Screwdriver for 3D Printer Controller Mother Boards Reprap MKS Prusa i3 Ender-3 Pro

I upgraded my DIY motorized blinds from DRV8825 to the TMC2208 and I am amazed at how much quieter these are than the DRV's. I mean, it is night and day. And they are almost 100% pin compatible. There is no sleep or reset pin on these but the step, direction, enable, microstep, motor,and voltage pins are all the same. One limitation though, the only way to go into full-step mode is to use them in UART, which I didn't want to go to the trouble to do so I am running them in half-step mode and they are still just as quiet. Just apply your VCC to the MS1 pin to get the 1/2 step setup.Also, they probably wouldn't have been a problem but it appeared to me that the solder joints on the top of the pins got too close to the heatsink for my comfort. So I trimmed them with my micro-cutters before applying the heat-sink to give extra clearance, just in case. And you will need the heatsinks. These do get much hotter than the DRV's.

These TMC2209's saved me from upgrading to SKR controller. They are very quite and smooth on the Ramps 1.4 controller. On mine the tiny pot looked liked it wasn't turning or adjusting ref voltage. Looking close I found I needed a small flat blade screwdriver to get snug in the slot. Adjusted all three (I already had one on hand) to about 0.6 volts. Great upgrade any easy to do.

These come in their own individual anti-static baggie with a screwdriver and a large aluminum heatsink that you have to stick on.They work great on my Anycubic Mega S 3D Printer and plug directly in where the old ones go, but you will have to swap the Motor 1 and Motor 2 phases on the motor connector that connects to them if you are doing something similar.The heat sink also sticks up higher than anything that it might replace, so you may have to modify cooling fan brackets and similar depending on what type of equipment you are installing these into.

It took a while to get it properly configured with my arduino, but it is running fine now. It is so quiet that I didn't know that it was working for a while since I thought that I would hear it. I added a flag on my stepper and saw it moving.You have to ground the enable pin which is what held me up.

These are amazing. I wish I would have upgraded to them sooner. They’re a drop in replacement for the A4988 drivers and make the printer SO MUCH QUIETER. I really wonder why I waited so long seeing as they’re so inexpensive. I only upgraded my x and y axis since the extruder and z axis don’t really make noise anyway.

Not much more to say. Works as described, absolutely silent upgrade for 3D printer stepper drivers.

The driver comes with a screwdriver and heat sink and does seem to work. The problem is adjusting the current to the stepper motor. The screwdriver does fit into the hole, but the potentiometer was not designed to adjust from the top of the board. The only way to adjust is from the bottom and you can’t do that when it’s inserted into the socket on the main board. Not sure how to make the proper adjustments.

One of the motor driver doesn't work appropriately.
